SIGNALING APPARATUS.

To all whom it mag concern Be it known that I, EDUARD LISSAUER, subjectof the German Emperor, residing at 167/168 Uhland'strasse,Gharlottenburg, Gerantl useful Improvements in Signaling Apparatus, ofwhich the following is a specification.

This invention relates to an apparatus for indicating the direction in,which a vehicle is about to turn. v

It has for its object to serve as safety means in street traflic inenabling thedriver of the vehicle to give a. signal, whereby thedirection in which the vehicle is about to turn can be made known orsignalized to the drivers of the vehicles behind or in front in order toprevent a collision of the vehicles.

In connection with the apparatus, the

movement of the signaling arm is eflected.

in the known manner in that locking .means are released, whereupon thesignaling arm assumes the signaling position under the action of its ownweight, a spring or the like.

According to the invention, the signaling arm is elastically buffered insuch amanner that it only assumes its final.position after it hasundergone several clearly visible upward and downwardswinging-movements, Due attention isthus attracted to the signaling. Forthe purpose of attracting attention, a mirror may also be combined withthe signaling arms, whereby by the reflection of light especially in thedark 2'. .c. by the refiection of lamp lights, the signal can thus berendered more effective.

Referring to the accompanying drawing, Figure 1 shows a form ofconstruction, according to which the adjustable signaling arm f isprovided on the left and'right side of an automobile. The rods 1" r,which are usually provided on the'right and left of the drivers seat,constitute suitable means for enabling the apparatus to be attached onboth sides, so that the signaling arms or indicating wings f can beswung outwardly on the left or right in a clearly visible posi- .tionand thus give a signal similarly as when the automobile driver produceswith his hand on the right or left the warning signal for the vehiclesbehind.

The apparatus is shown in Figs. 2, 3 and 4, Fig. 2 shows the apparatus(in combination with a Bowden mechanism) provided on the left side, Fig.3 is a side elevation and Fig. 4: a plan with respectto Fig. 2,

The signaling arm fis fulcrumed ate in.

a bracket a which in the form of 'a two-part:

clip can be secured to the rod 2" or the like (Figs. 14).. A member battached to the bracket a forms a vertical guide fora rod,

downwardly actingengaging means for the knee-shaped lever is which'issecured to the signaling arm f and extends through the fork g. v

As is obvious from Fig. 2, the downward pull of the rod d, Which/cakesplace in opposition to theliftin tendency of the spring j, elfects bymeans 0 4 the fork g and roller 2' a tilting or upward swinging of thesignaling wing f outof the indicating position as shown until'it assumesa position of rest as shown in dotted lines, the lever is being firmlyheld beneath the roller 2'. In this position of the parts, the apparatusassumes the position in which it is ready for being rendered operativeafter the releasing action;

The connection with the known Bowden mechanism is such (Fig. 2) thatthere is connected to the lower, end of the rod (13 the wire-shapedpulling member a which is surrounded by the tubular non-compressiblemember s and that this pulling power transmitter is connected to anadjusting lever h in the known manner. When shifting the adjusting leverit into the position indicated by dotted lines, the pull of the pullingmember 2 takes place to thesame extent as the lift of the rod d. In thefinal or end position, a spring pawl o of the adjusting lever engages ina notch u of the fixed part, so that the rearward movement (under thecompulsion of the spring j) cannot take place of its own accord, Thisapparatus is supposed to be provided near to the steering means of theautomobile or it can be combined with the steering mechanism. It canroller 21 moves upward on the spring being released or relieved. Thereleased signal- It is immediately reversed a .or shifted because thespring j acts on the pulling rods and the rod d with fork g and tendedposition in the upward movement of the arm, so that pose with greatersafety.

ing arm f therefore swings into a position as shown but owing to thepresence of a flexible support such as a spring-0 (Fig. 2), it cannotattain its end or final position without previously performing a clearlyvisible rocking movement. The spring ois a retractile spring, which isshown in its ex- Fig. 2. WVhen the sig naling arm is moved upwardly thespring o will shorten to an extent corresponding to whenthe arm is insubstantially vertical position (dottedline position of Fig.2) thespring will have attained its --normal, compressed, state. Thisrepeating rot ing-imovement attracts special attention to lthe givensignal. In order to also render the signaling conspicuous in thedark, itisad visable to provide amirror a" on the sig naling arm (Fig. 2). Byspecial lighting means or bythe reflection of the existing lamp lights,such mirror, which may either, be a plane, convex or concave mirror, is?adapted to efl'ectively attract attention to the operation of thesignaling apparatus, which is attained by the rocking movement of the;arm, so that the apparatus fulfils its pur It is obvious that theapparatus may also be usedfor other signaling purposes.
